After big snow and ice events in the Southeast, Plains, and Midwest this week, 49 out of the 50 states currently have snow on the ground – yes, even Hawaii, where snow falls in Mauna Loa and Mauna Kea all winter.
The only state that has avoided this icy blast is Florida. Does that make you want to go on a nice, warm vacation to the Sunshine State? You're not alone.
Put another way, that means snow is present in 69.4 percent of the lower 48, which is more than double than December. This is extremely unusual, though it's hard to put a date on when this last happened because records aren't kept on this kind of event.
The National Operational Hydrologic Remote Sensing Center combines ground reports and images from satellites in space to determine how much of the country is covered in snow. That's what you see in the image above. The images tell how deep and widespread the snow is, and that's important not only for images like this one, but also for computer weather models, which use the data to generate accurate forecasts. Such forecasts were very useful in predicting this week's winter storms.
Earlier this week, two storms began to churn: one in the northern Plains and Midwest, and one in Texas. The southern winter storm took a track across the Gulf Coast, pulling warm, moist air over an extreme arctic blast that set up over the eastern half of the United States late last week. This provided fuel for the storm to carve a path of snow, sleet, and freezing rain from Texas to the Carolinas.
Here in Atlanta, we're still coated in snow and ice and probably will be for the next couple of days. No one in the Southeast escaped the wrath except, of course, Florida.
But it's not over. Now that the southern-track storm has moved into the Atlantic and is moving north, the other Midwest storm is going to merge with it, creating a Nor'easter event that could dump up to two feet of snow in the Northeast. Winter storm warnings and advisories have been posted for the event - 32 states have winter storm advisories issued, by the way.
Here's how the snow forecast breaks down for some major cities:
Washington DC: 2-4 inches
Philadelphia, Pennsylvania: 4-6 inches
New York, N.Y.: 6-12 inches
Hartford, Connecticut: 15-20 inches
Boston, Massachusetts: 12-16 inches
The snow and cold started early this winter and has been extreme for most of the country. Usually the Southeast avoids the blast, but not in 2011. We're all feeling a little "snowed in" this winter.
